Abstract
The utility model discloses a pump cover drill jig which comprises a drill jig plate arranged on a pump cover, the drill jig plate comprises a long and round plate body, a circle of flanging is arranged on the edge of the lower side of the long and round plate body, the inner side of flanging and the lower side face of the long-round plate body form a groove, the long-round plate body of the drill jig plate is provided with a plurality of drill bushing holes which are evenly distributed in the long and round circumference, drill bushings are arranged in the drill bushing holes, the drill bushings are in transition fit with the drill bushing holes, and a locating inserting pin is arranged in one drill bushing. The upper side face of the pump cover is of a long and round structure, and the groove of the drill jig plate is arranged in the pump cover in a sleeved mode, so that the drill jig plate is located on the pump cover; the positions of the drill bushings on the drill jig plate are the positions of drill holes in the pump cover. Drilling can be carried out without proofing punch, labor intensity of workers is reduced, and work efficiency is improved. The drill bushing holes and the drill bushings on the drill jig plate are high in position accuracy, the drill holes also are high in position accuracy, and product quality is improved.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of pump cover drill jig.
Background technology
Pump cover is part conventional in pump series products, for pump cover is connected with the pump housing, need on pump cover, process some through holes, with bolt, through through hole, two parts is connected.When small lot batch manufacture, frequent first center-punching on part is then holed on drilling machine, but when producing in enormous quantities, center-punching is wasted time and energy, and operating efficiency is low, and labor strength is large, and the positional precision that center-punching is holed is low, affects product quality.
Utility model content
Problem to be solved in the utility model is, for the defect of prior art, provides a kind of pump cover drill jig, can increase work efficiency, and reduces labor strength, improves the positional precision in hole, improves the quality of products.
The purpose of this utility model is achieved through the following technical solutions.A kind of pump cover drill jig, comprise the bushing plate being arranged on pump cover, described bushing plate comprises a Long Circle plate, the edge of Long Circle plate downside is provided with a circle flange, and the downside of the inner side of flange and Long Circle plate forms a groove, and the Long Circle plate of bushing plate is provided with some drill bushings hole, drill bushing hole is distributed on a Long Circle circumference, drill bushing is provided with drill bushing in hole, and drill bushing and drill bushing hole interference fits, be provided with fastening screw in one of them drill bushing.The upper side of pump cover is Long Circle structure, and the groove part of bushing plate is inserted in to pump cover, and bushing plate locates on pump cover, on bushing plate, the position of drill bushing is exactly the position of holing on pump cover, do not need center-punching to hole, reduced labor strength, improved operating efficiency.And the positional precision of drill bushing hole and drill bushing is high on bushing plate, the positional precision of holing is also high, has improved product quality.
As preferably, described fastening screw comprises columniform location division, and the upside of location division is provided with columniform back-up ring, and the upside of back-up ring is provided with columniform Handheld Division, and location division, back-up ring and the Handheld Division structure that is formed in one is simple in structure, easy to use.
As preferably, described Long Circle plate centre position is provided with a lightening hole, has alleviated the weight of bushing plate, and operation easily.
Main beneficial effect of the present utility model is, improved operating efficiency, reduced labor strength, improved the positional precision in hole, improved product quality.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model bushing plate.
The specific embodiment
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
As shown in Figure 1 to Figure 2, a kind of pump cover drill jig, comprise the bushing plate 1 being arranged on pump cover 6, described bushing plate comprises a Long Circle plate, and the edge of Long Circle plate downside is provided with a circle flange 5, the downside of the inner side of flange and Long Circle plate forms a groove, the Long Circle plate of bushing plate is provided with 6 drill bushing holes 7, and drill bushing hole is distributed on a Long Circle circumference, in each drill bushing hole, is equipped with drill bushing 3, drill bushing and drill bushing hole interference fits, be provided with fastening screw 2 in one of them drill bushing.Described fastening screw comprises columniform location division, and the upside of location division is provided with columniform back-up ring, and the upside of back-up ring is provided with columniform Handheld Division, location division, back-up ring and the Handheld Division structure that is formed in one.Described Long Circle plate centre position is provided with a lightening hole 4.Because the aperture of holing on pump cover is less than φ 10, so process on bench drill.Operating procedure is as follows: 1. pump cover is placed on the workbench of drilling machine, needs one of boring to face up; 2. by bushing plate groove part down, groove is inserted in pump cover upside, and bushing plate is located on pump cover; 3. with hand, live bushing plate, start drilling machine, drill bit is aimed at drill bushing and is bored first hole; 4. in hole-drilled position, insert fastening screw, bore all the other 5 holes; 5. fastening screw is taken off from bushing plate, then bushing plate is taken off from pump cover, process next part.
The above is the preferably specific embodiment of the utility model, not with this, limits practical range of the present utility model.The utility model can also have other embodiment, only otherwise deviate from spirit of the present utility model, and within no matter in form what kind of conversion all drops on protection domain of the present utility model.
